Transport request between SAP systems with different versions
I have to synchronize the customizing and workbench objects of two existing development systems, which have different versions (EHP3 and EHP4). First I thought, that I can do this by importing the existing transport requests.
Now I`ve heard, that this isn`t recommended. even more it would be dangerous to do a transport from one system to another system with a different version. Can someone explain, which problems can occur and which risks exists?
